 - Backends: SDL2: removed unnecessary SDL_Window* parameter from ImGui_ImplSDL2_NewFrame(). (#3244) [@funchal]
   Kept inline redirection function (will obsolete).
+- Commented out redirecting functions/enums names that were marked obsolete in 1.67 and 1.69 (March 2019):
+  - ImGui::GetOverlayDrawList() -> use ImGui::GetForegroundDrawList()
+  - ImFont::GlyphRangesBuilder  -> use ImFontGlyphRangesBuilder
 - Internals: (for custom widgets): because disabled items now sets HoveredId, if you want custom widgets to
   not react as hovered when disabled, in the majority of use cases it is preferable to check the "hovered"
   return value of ButtonBehavior() rather than (HoveredId == id).

                         - if you are using official backends from the source tree: you have nothing to do.
                         - if you have copied old backend code or using your own: change access to draw_cmd->TextureId to draw_cmd->GetTexID().
